Optiarc AD-7173A

I have 2 x Optiarc AD-7173A with 1.03 Firmware
Im going to Backup PS2 Games with these and i would like to know are these reliable burners at speed 4x, nothing is more annoying then playing ps2 game and then it starts to lag because of bad burn.
Media im going to use is Verbatim DVD+R Azo.

I don’t know anything about the drive but you should not use DVD+ Media for your ps2.
The ps2 Drive is made for DVD- media. Verbatim DVD- is a very good choice.
